BACKGROUND OF THE INVENTION

The search for new therapeutic agents has been greatly aided in recent years by a better understanding of the structure of enzymes and other biomolecules associated with diseases. One important class of enzymes that has been the subject of intensive study is protein kinases.

Protein kinases constitute a large family of structurally related enzymes that are responsible for the control of a variety of signal transduction processes within the cell (see Hardie, G. and Hanks, S. The Protein Kinase Facts Book, I and II, Academic Press, San Diego, Calif.: 1995). Protein kinases are thought to have evolved from a common ancestral gene due to the conservation of their structure and catalytic function. Almost all kinases contain a similar 250-300 amino acid catalytic domain. The kinases may be categorized into families by the substrates they phosphorylate (e.g., protein-tyrosine, protein-serine/threonine, lipids etc). Sequence motifs have been identified that generally correspond to each of these kinase families (See, for example, Hanks, S. K., Hunter, T., FASEB J. 1995, 9, 576-596; Knighton et al., Science 1991, 253, 407-414; Hiles et al, Cell 1992, 70, 419-429; Kunz et al, Cell 1993, 73, 585-596; Garcia-Bustos et al, EMBO J. 1994, 13, 2352-2361).

In general, protein kinases mediate intracellular signaling by effecting a phosphoryl transfer from a nucleoside triphosphate to a protein acceptor that is involved in a signaling pathway. These phosphorylation events act as molecular on/off switches that can modulate or regulate the target protein biological function. These phosphorylation events are ultimately triggered in response to a variety of extracellular and other stimuli. Examples of such stimuli include environmental and chemical stress signals (e.g., shock, heat shock, ultraviolet radiation, bacterial endotoxin, and H₂O₂), cytokines (e.g., interleukin-1 (IL-1) and tumor necrosis factor alpha (TNF-a), and growth factors (e.g., granulocyte macrophage-colony stimulating factor (GM-CSF), and fibroblast growth factor (FGF)). An extracellular stimulus may affect one or more cellular responses related to cell growth, migration, differentiation, secretion of hormones, activation of transcription factors, muscle contraction, glucose metabolism, control of protein synthesis, survival and regulation of the cell cycle.

Many diseases are associated with abnormal cellular responses triggered by protein kinase-mediated events as described above. These diseases include, but are not limited to, cancer, autoimmune diseases, inflammatory diseases, bone diseases, metabolic diseases, neurological and neurodegenerative diseases, cardiovascular diseases, allergies and asthma, Alzheimer's disease and hormone related diseases. Accordingly, there has been a substantial effort in medicinal chemistry to find protein kinase inhibitors that are effective as therapeutic agents.

The Polo-like kinases (Plk) belong to a family of serine/threonine kinases that are highly conserved across the species, ranging from yeast to man (reviewed in Lowery D M et al., Oncogene 2005, 24; 248-259). The Plk kinases have multiple roles in cell cycle, including control of entry into and progression through mitosis.

Plk1 is the best characterized of the Plk family members. Plk1 is widely expressed and is most abundant in tissues with a high mitotic index. Protein levels of Plk1 rise and peak in mitosis (Hamanaka, R et al., J Biol Chem 1995, 270, 21086-21091). The reported substrates of Plk1 are all molecules that are known to regulate entry and progression through mitosis, and include CDC25C, cyclin B, p53, APC, BRCA2 and the proteasome. Plk1 is upregulated in multiple cancer types and the expression levels correlate with severity of disease (Macmillan, J C et al., Ann Surg Oncol 2001, 8, 729-740). Plk1 is an oncogene and can transform NIH-3T3 cells (Smith, M R et al., Biochem Biophys Res Commun 1997, 234, 397-405). Depletion or inhibition of Plk1 by siRNA, antisense, microinjection of antibodies, or transfection of a dominant negative construct of Plk1 into cells, reduces proliferation and viability of tumour cells in vitro (Guan, R et al., Cancer Res 2005, 65, 2698-2704; Liu, X et al., Proc Natl Acad Sci USA 2003, 100, 5789-5794, Fan, Y et al., World J Gastroenterol 2005, 11, 4596-4599; Lane, H A et al., J Cell Biol 1996, 135, 1701-1713). Tumour cells that have been depleted of Plk1 have activated spindle checkpoints and defects in spindle formation, chromosome alignment and separation and cytokinesis. Loss in viability has been reported to be the result of an induction of apoptosis. In contrast, normal cells have been reported to maintain viability on depletion of Plk1. In vivo knock down of Plk1 by siRNA or the use of dominant negative constructs leads to growth inhibition or regression of tumours in xenograft models.

Plk2 is mainly expressed during the G1 phase of the cell cycle and is localized to the centrosome in interphase cells. Plk2 knockout mice develop normally, are fertile and have normal survival rates, but are around 20% smaller than wild type mice. Cells from knockout animals progress through the cell cycle more slowly than in normal mice (Ma, S et al., Mol Cell Biol 2003, 23, 6936-6943). Depletion of Plk2 by siRNA or transfection of kinase inactive mutants into cells blocks centriole duplication. Downregulation of Plk2 also sensitizes tumour cells to taxol and promotes mitotic catastrophe, in part by suppression of the p53 response (Burns T F et al., Mol Cell Biol 2003, 23, 5556-5571).

Plk3 is expressed throughout the cell cycle and increases from G1 to mitosis. Expression is upregulated in highly proliferating ovarian tumours and breast cancer and is associated with a worse prognosis (Weichert, W et al., Br J Cancer 2004, 90, 815-821; Weichert, W et al., Virchows Arch 2005, 446, 442-450). In addition to regulation of mitosis, Plk3 is believed to be involved in Golgi fragmentation during the cell cycle and in the DNA-damage response. Inhibition of Plk3 by dominant negative expression is reported to promote p53-independent apoptosis after DNA damage and suppresses colony formation by tumour cells (Li, Z et al., J Biol Chem 2005, 280, 16843-16850.

Plk4 is structurally more diverse from the other Plk family members. Depletion of this kinase causes apoptosis in cancer cells (Li, J et al., Neoplasia 2005, 7, 312-323). Plk4 knockout mice arrest at E7.5 with a high fraction of cells in mitosis and partly segregated chromosomes (Hudson, J W et al., Current Biology 2001, 11, 441-446).

Molecules of the protein kinase family have been implicated in tumour cell growth, proliferation and survival. Accordingly, there is a great need to develop compounds useful as inhibitors of protein kinases. The evidence implicating the Plk kinases as essential for cell division is strong. Blockade of the cell cycle is a clinically validated approach to inhibiting tumour cell proliferation and viability. It would therefore be desirable to develop compounds that are useful as inhibitors of the Plk family of protein kinases (e.g., Plk1, Plk2, Plk3 and Plk4), that would inhibit proliferation and reduce viability of tumour cells, particularly as there is a strong medical need to develop new treatments for cancer, including treatments that would be administered orally.

In certain embodiments, a protecting group has one or more, or preferably all, of the following characteristics: a) is added selectively to a functional group in good yield to give a protected substrate that is b) stable to reactions occurring at one or more of the other reactive sites; and c) is selectively removable in good yield by reagents that do not attack the regenerated, deprotected functional group. As would be understood by one skilled in the art, in some cases, the reagents do not attack other reactive groups in the compound. In other cases, the reagents may also react with other reactive groups in the compound. Exemplary protecting groups are detailed in Greene, T. W., Wuts, P. G in “Protective Groups in Organic Synthesis”, Third Edition, John Wiley & Sons, New York: 1999 (and other editions of the book), the entire contents of which are hereby incorporated by reference. The term “nitrogen protecting group”, as used herein, refers to an agents used to temporarily block one or more desired nitrogen reactive sites in a multifunctional compound. Preferred nitrogen protecting groups also possess the characteristics exemplified above, and certain exemplary nitrogen protecting groups are also detailed in Chapter 7 in Greene, T. W., Wuts, P. G in “Protective Groups in Organic Synthesis”, Third Edition, John Wiley & Sons, New York: 1999, the entire contents of which are hereby incorporated by reference.

In some embodiments, an alkyl or aliphatic chain can be optionally replaced with another atom or group. This means that a methylene unit of the alkyl or the aliphatic chain is optionally replaced with said other atom or group. Examples of such atoms or groups would include, but are not limited to, —NR—, —O—, —C(O)—, —C(═N—CN)—, —C(═NR)—, —C(═NOR)—, —S—, —SO—, or —SO₂—. These atoms or groups can be combined to form larger groups. Examples of such groups include, but are not limited to, —OC(O)—, —C(O)CO—, —CO₂—, —C(O)NR—, —C(═N—CN), —NRCO—, —NRC(O)O—, —SO₂NR—, —NRSO₂—, —NRC(O)NR—, —OC(O)NR—, and —NRSO₂NR—, wherein R is defined herein.

Unless otherwise specified, the optional replacements form a chemically stable compound. Optional replacements can occur both within the chain and at either end of the chain; i.e., both at the point of attachment and/or also at the terminal end. Two optional replacements can also be adjacent to each other within a chain so long as it results in a chemically stable compound. The optional replacements can also completely replace all of the carbon atoms in a chain. For example, a C₃ aliphatic can be optionally replaced by —NR—, —C(O)—, and —NR— to form —NRC(O)NR— (a urea).

Unless otherwise specified, if the replacement occurs at the terminal end, the replacement atom is bound to an H on the terminal end. For example, if —CH₂CH₂CH₃ were optionally replaced with —O—, the resulting compound could be —OCH₂CH₃, —CH₂OCH₃, or —CH₂CH₂OH.

Unless otherwise stated, structures depicted herein are also meant to include all isomeric (e.g., enantiomeric, diastereomeric, geometric, conformational, and rotational forms of the structure). For example, the R and S configurations for each asymmetric center, (Z) and (E) double bond isomers, and (Z) and (E) conformational isomers are included in this invention. As would be understood to one skilled in the art, a substituent can freely rotate around any rotatable bonds. For example, a substituent drawn as

also represents

Therefore, single stereochemical isomers as well as enantiomeric, diastereomeric, geometric, conformational, or rotational mixtures of the present compounds are within the scope of the invention.

Unless otherwise stated, all tautomeric forms of the compounds of the invention are within the scope of the invention.

Additionally, unless otherwise stated, structures depicted herein are also meant to include compounds that differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures except for the replacement of hydrogen by deuterium or tritium, or the replacement of a carbon by a ¹³C- or ¹⁴C-enriched carbon are within the scope of this invention. Such compounds are useful, for example, as analytical tools or probes in biological assays.

I-287 General Synthetic Methodology

The compounds of this invention may be prepared in general by methods such as those depicted in the general schemes below, and the preparative examples that follow. Unless otherwise indicated, all variables in the following schemes are as defined herein.

Scheme 1 above shows a general synthetic route for preparing compounds of formula I where Y¹=O. Starting material 1 (wherein LG₁ and LG₂ can be, but not restricted to, chlorine atoms) reacts with β-aminoester 2 to give adduct 3. Reduction of the nitro group, followed by cyclo-condensation gives bicyclic compound 4. The amide N—H can be functionalized at this stage to give 5. LG₂ can finally be used as a handle for preparation of the compounds of formula I. In this last step LG₂ can, for example, be displaced with amines or be engaged in palladium assisted coupling reactions known to one skilled in the art (e.g., Suzuki, Stille).

Alternatively, the compound of formula 3, after reduction of the nitro group, can be first functionalized to form a compound of formula 3-b;

which can subsequently be cyclized to form the compound of formula 5.

Scheme 2 above shows a general synthetic route for preparing compounds of this invention where Y² is NR⁹. The lactam functional group in 5 or I (either in 5 where LG₂ is still present or in I if it has already been derivatised as R¹X¹) can be engaged into a functional group transformation to form an amidine group (either 5-a where LG₂ is still present or I-a if it has already been derivatised as R¹X¹).

Alternatively, Scheme 2 above also shows a general synthetic route for preparing compounds of this invention where Y²=N and R² and R⁹ are taken together to form ring A. The lactam functional group in 5 or I (either in 5 where LG₂ is still present or in I if it has already been derivatised as R¹X¹) can be engaged in a multi-step cyclisation sequence to form ring A (either 5-b where LG₂ is still present or I-b if it has already been derivatised as R¹X¹).

Scheme 3 above shows a general synthetic route for preparing compounds of this invention where Y¹ is NR⁹ and R² and R⁹ are taken together to form a triazole ring. Activation of the lactam functional group in 4, followed by displacement with hydrazine lead to intermediates of formula 7. Compounds of formula I-b were finally obtain by cyclisation of derivatives 7 and subsequent displacement with HX₁—R₁.

Scheme 4 above shows another general synthetic route for preparing compounds 5 of this invention. Compounds of formula 5a, containing a protecting group on the amine, can be prepared like previously shown (see compound 5 scheme 1). Deprotection of amines 5a, followed by substitution of the free amines of 9 with the desired R⁷-halides can be achieved by methods well known in the art.

Accordingly, this invention also provides a process for preparing a compound of this invention.

One embodiment of this invention provides a process for preparing a compound of formula I:

wherein Y¹ is O and X¹, R¹, R², R³, R⁴, R⁵, R⁶, and R⁷ are as defined herein; comprising reacting a compound of formula 5;

wherein R², R³, R⁴, R⁵, R⁶, and R⁷ are as defined herein; and LG₂ is a suitable leaving group, such as halo, with X1R1 under suitable conditions to form the compound of formula I. X1R1 can displace LG₂ in a variety of ways known to one skilled in the art. For example, if X¹ is NHR⁸, O, or S, then X¹R¹ can displace LG₂ in the presence of suitable base or acid, solvent, and conditions. Suitable displacement reactions are known to one skilled in the art and can be found in a variety of resources, including “March's Advanced Organic Chemistry”. A sulfur linker (wherein X¹ is S) can be oxidized under suitable oxidation conditions to form compounds wherein X¹ is SO or SO₂. Compounds of formula I, wherein X¹ is a bond and R¹ is bonded to X¹ via a carbon atom, can be formed under suitable cross-coupling conditions. In these cross coupling reactions, one of the starting materials is R¹ bonded to a cross-coupling group. This starting material can react with the compound of formula 5 under cross coupling conditions to form compounds of formula I, wherein X¹ is a bond and R¹ is bonded to X¹ via a carbon atom.

The term “cross-coupling reaction”, as used herein, refers to a reaction in which a carbon-carbon bond is formed with the aid of a metal catalyst. Usually, one of the carbon atoms is bonded to a functional group (a “cross-coupling group”) while the other carbon atom is bonded to a halogen. Examples of cross coupling reactions include, but are not limited to, Suzuki couplings, Stille couplings, and Negishi couplings.

The term “cross-coupling group”, as used herein, refers to a functional group capable of reacting with another functional group (e.g., halo) in a cross coupling reaction to form a carbon-carbon (“C—C”) bond. In some embodiments, the C—C bond is formed between two aromatic groups.

The term “cross coupling condition”, as used herein, refers to the chemical conditions (e.g., temperature, length of time of reaction, volume of solvent required) required in order to enable the cross coupling reaction to occur.

Examples of cross-coupling groups and their respective cross-coupling conditions include, but are not limited to, boronic acids and boronic esters with Suzuki coupling conditions, SnBu₃ with Stille coupling conditions, and ZnX with Negishi coupling conditions.

All three of these coupling conditions typically involve the use of a catalyst, a suitable solvent, and optionally a base. Suzuki coupling conditions involve the use of a palladium catalyst and a suitable solvent. Examples of suitable palladium catalysts include, but are not limited to, PdCl₂(PPh₂)₂, Pd(Ph₃)₄, and PdCl₂(dppf). Suitable bases include, but are not limited to, K₂CO₃ and Na₂CO₃. Suitable solvents include, but are not limited to, tetrahydrofuran, toluene, and ethanol.

Stille coupling conditions involve the use of a catalyst (usually palladium, but sometimes nickel), a suitable solvent, and other optional reagents.

Another embodiment provides a process for forming a compound of formula 5 comprising reacting a compound of formula 4;

wherein R³, R⁴, R⁵, R⁶, and R⁷ are as defined herein; and LG₂ is a suitable leaving group, such as halo; with R²-LG₂, wherein LG₂ is a leaving group capable of being displaced by an NH-amide. Examples of leaving groups include, but are not limited to, halo, tosylate, and mesylate.

Another embodiment provides a process for forming a compound of formula 4 comprising reacting a compound of formula 3;

under a two step process. The first step involves reduction of the nitro group under suitable reduction conditions, such as iron powder, SnCl₂, zinc powder, indium/HCl, or H₂/Pd to form a compound of formula 3-a:

The second step involves cyclocondensation of the amine with the carboxylic ester of formula 3-a, resulting in the compound of formula 4. Cyclocondensations typically occur in the presence of an acid or a base. In some embodiments, this two-step process occurs in situ. One example of an in situ condition involves treating the nitro-compound with iron powder in glacial acetic acid.

Another aspect of this invention provides an alternative way of forming the compounds of formula 5. Instead of directly cyclizing the compound of formula 3-a to form the compound of formula 4, the amino intermediate can be functionalized first to form the compound of formula 3-b

under suitable conditions known to one skilled in the art. For example, the amino group can react with R²-LG₃, wherein LG₃ is a leaving group capable of being displaced by an amine. Examples of leaving groups include, but are not limited to, halo, tosylate, and mesylate. This compound can then be cyclized under suitable cyclocondensation conditions to form the compound of formula 5.

Another embodiment of this invention provides a process for forming the compound of formula 3; comprising reacting the compound of formula 2;

with a compound of formula 1;

under suitable displacement conditions to form the compound of formula 3. Suitable displacement conditions typically comprise of a suitable solvent and a suitable base or acid. Examples of suitable displacement conditions include, but are not limited to, K₂CO₃ and acetone, Hunig's base/THF.

Another aspect of this invention provides a process for making compounds of formula I wherein Y¹ is NR⁹. One embodiment involves reacting the compound of formula I wherein Y¹ is O and X¹, R¹, R², R³, R⁴, R⁵, R⁶, and R⁷ are as defined herein; under suitable conditions known in the art for converting amides into amidines, to form a compound of formula I wherein Y¹ is NR⁹ (shown in Scheme II as I-a). Suitable conditions typically involve an amine (R¹—NHR⁹), a suitable solvent, and an activated intermediate deriving from an amide (e.g., a thioamide prepared from an amide and Lawesson's Reagent).

In another aspect, the compound of formula 5 can be subject to similar amide-converting conditions to form a compound of formula 5-a. The LG₂ group in 5-a or 5-b can be used as a handle for preparation of the compounds of this invention. In this last step LG₂ can, for example, be displaced with amines or be engaged in palladium assisted coupling reactions (e.g., Suzuki, Stille).

In some embodiments, the compounds of formula I or 5, wherein Y¹ is O and X¹, R¹, R², R³, R⁴, R⁵, R⁶, and R⁷ are as defined herein, can be converted into cyclic amidines, wherein R² and R⁹ are taken together to form ring A. These cyclic amidines (shown in Scheme II as I-b) can be made via a multi-step cyclisation sequence. Ring A can vary in size (e.g. 5-8 membered ring) and in degree of unsaturation. For example, formation of ring A can be carried out using methods similar to the ones reported in: J. Am. Chem. Soc, 103 (14), 4186-4194, 1981; J. Het. Chem., 19(1), 193-200, 1982; Angew. Chem., 43(4), 478-482, 2004; Scientia Pharm., 57(1), 27-38, 1989; Tetrahedron Lett., 16(2), 449-469, 2005; J. Org. Chem., 59 (17), 5084-5087, 1994. The LG₂ group in 5-a or 5-b can be used as a handle for preparation of the compounds of this invention. In this last step LG₂ can, for example, be displaced with amines or be engaged in palladium assisted coupling reactions (e.g., Suzuki, Stille).

In some embodiments, said protein kinase-mediated condition is a PLK-mediated condition.

The exact amount of compound required for treatment will vary from subject to subject, depending on the species, age, and general condition of the subject, the severity of the infection, the particular agent, its mode of administration, and the like. The compounds of the invention are preferably formulated in dosage unit form for ease of administration and uniformity of dosage. The expression “dosage unit form” as used herein refers to a physically discrete unit of agent appropriate for the patient to be treated. It will be understood, however, that the total daily usage of the compounds and compositions of the present invention will be decided by the attending physician within the scope of sound medical judgment. The specific effective dose level for any particular patient or organism will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed, and like factors well known in the medical arts. The term “patient”, as used herein, means an animal, preferably a mammal, and most preferably a human.

The pharmaceutically acceptable compositions of this invention can be administered to humans and other animals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), bucally, as an oral or nasal spray, or the like, depending on the severity of the infection being treated. In certain embodiments, the compounds of the invention may be administered orally or parenterally at dosage levels of about 0.01 mg/kg to about 50 mg/kg and preferably from about 1 mg/kg to about 25 mg/kg, of subject body weight per day, one or more times a day, to obtain the desired therapeutic effect. In a preferred embodiment, compounds of this invention are administered orally.

Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.

Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides.

The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.

In order to prolong the effect of a compound of the present invention, it is often desirable to slow the absorption of the compound from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the compound then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered compound form is accomplished by dissolving or suspending the compound in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the compound in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of compound to polymer and the nature of the particular polymer employed, the rate of compound release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the compound in liposomes or microemulsions that are compatible with body tissues.

Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound.

In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.

Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polethylene glycols and the like.

In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes.

Dosage forms for topical or transdermal administration of a compound of this invention include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. The active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required. Ophthalmic formulation, eardrops, and eye drops are also contemplated as being within the scope of this invention. Additionally, the present invention contemplates the use of transdermal patches, which have the added advantage of providing controlled delivery of a compound to the body. Such dosage forms can be made by dissolving or dispensing the compound in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate can be controlled by either providing a rate controlling membrane or by dispersing the compound in a polymer matrix or gel.

Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose, any bland fixed oil may be employed including synthetic mono- or di-glycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions may also contain a long-chain alcohol diluent or dispersant, such as carboxymethyl cellulose or similar dispersing agents which are commonly used in the formulation of pharmaceutically acceptable dosage forms including emulsions and suspensions. Other commonly used surfactants, such as Tweens, Spans and other emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or other dosage forms may also be used for the purposes of formulation.

The pharmaceutical compositions of this invention may be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, aqueous suspensions or solutions. In the case of tablets for oral use, carriers commonly used include, but are not limited to, lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried cornstarch. When aqueous suspensions are required for oral use, the active ingredient is combined with emulsifying and suspending agents. If desired, certain sweetening, flavoring or coloring agents may also be added.

Alternatively, the pharmaceutical compositions of this invention may be administered in the form of suppositories for rectal administration. These can be prepared by mixing the agent with a suitable non-irritating excipient that is solid at room temperature but liquid at rectal temperature and therefore will melt in the rectum to release the drug. Such materials include, but are not limited to, cocoa butter, beeswax and polyethylene glycols.

The pharmaceutical compositions of this invention may also be administered topically, especially when the target of treatment includes areas or organs readily accessible by topical application, including diseases of the eye, the skin, or the lower intestinal tract. Suitable topical formulations are readily prepared for each of these areas or organs.

Topical application for the lower intestinal tract can be effected in a rectal suppository formulation (see above) or in a suitable enema formulation. Topically-transdermal patches may also be used.

For topical applications, the pharmaceutical compositions may be formulated in a suitable ointment containing the active component suspended or dissolved in one or more carriers. Carriers for topical administration of the compounds of this invention include, but are not limited to, mineral oil, liquid petrolatum, white petrolatum, propylene glycol, polyoxyethylene, polyoxypropylene compound, emulsifying wax and water. Alternatively, the pharmaceutical compositions can be formulated in a suitable lotion or cream containing the active components suspended or dissolved in one or more pharmaceutically acceptable carriers. Suitable carriers include, but are not limited to, mineral oil, sorbitan monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-octyldodecanol, benzyl alcohol and water.

For ophthalmic use, the pharmaceutical compositions may be formulated as micronized suspensions in isotonic, pH adjusted sterile saline, or, preferably, as solutions in isotonic, pH adjusted sterile saline, either with or without a preservative such as benzylalkonium chloride. Alternatively, for ophthalmic uses, the pharmaceutical compositions may be formulated in an ointment such as petrolatum.

The pharmaceutical compositions of this invention may also be administered by nasal aerosol or inhalation. Such compositions are prepared according to techniques well-known in the art of pharmaceutical formulation and may be prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, fluorocarbons, and/or other conventional solubilizing or dispersing agents.

The amount of protein kinase inhibitor that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated, the particular mode of administration. Preferably, the compositions should be formulated so that a dosage of between 0.01-100 mg/kg body weight/day of the inhibitor can be administered to a patient receiving these compositions.

It should also be understood that a specific dosage and treatment regimen for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, rate of excretion, drug combination, and the judgment of the treating physician and the severity of the particular disease being treated. The amount of inhibitor will also depend upon the particular compound in the composition.

According to another embodiment, the invention provides methods for treating or preventing a protein kinase-mediated condition (in some embodiments, a PLK-mediated condition) comprising the step of administering to a patient one of the above-described pharmaceutical compositions. The term “patient”, as used herein, means an animal, preferably a human.

In some embodiments, said method is used to treat or prevent a condition selected from a proliferative disorder, such as cancer, a neurodegenerative disorder, an autoimmune disorder, an inflammatory disorder, and an immunologically-mediated disorder.

Example 279 PLK1 Assay

The compounds of the present invention are evaluated as inhibitors of human PLK kinase using the following assays.

Plk1 Inhibition Assay:

Compounds were screened for their ability to inhibit Plk1 using a radioactive-phosphate incorporation assay. Assays were carried out in a mixture of 25 mM HEPES (pH 7.5), 10 mM MgCl₂, and 1 mM DTT. Final substrate concentrations were 50 μM [γ-33P]ATP (136 mCi 33P ATP/mmol ATP, Amersham Pharmacia Biotech/Sigma Chemicals) and 10 μM peptide (SAM68 protein Δ332-443). Assays were carried out at 25° C. in the presence of 15 nM Plk1 (A20-K338). An assay stock buffer solution was prepared containing all of the reagents listed above, with the exception of ATP and the test compound of interest. 30 μL of the stock solution was placed in a 96 well plate followed by addition of 2 μL of DMSO stock containing serial dilutions of the test compound (typically starting from a final concentration of 10 μM with 2-fold serial dilutions) in duplicate (final DMSO concentration 5%). The plate was pre-incubated for 10 minutes at 25° C. and the reaction initiated by addition of 8 μL [γ-33P]ATP (final concentration 50 μM).

The reaction was stopped after 60 minutes by the addition of 100 μL 0.14M phosphoric acid. A multiscreen phosphocellulose filter 96-well plate (Millipore, Cat no. MAPHN0B50) was pretreated with 100 μL 0.2M phosphoric acid prior to the addition of 125 μL of the stopped assay mixture. The plate was washed with 4×200 μL 0.2M phosphoric acid. After drying, 100 μL Optiphase ‘SuperMix’ liquid scintillation cocktail (Perkin Elmer) was added to the well prior to scintillation counting (1450 Microbeta Liquid Scintillation Counter, Wallac).

After removing mean background values for all of the data points, Ki(app) data were calculated from non-linear regression analysis of the initial rate data using the Prism software package (GraphPad Prism version 3.0cx for Macintosh, GraphPad Software, San Diego Calif., USA).

Plk1 Inhibition Assay:

Compounds were screened for their ability to inhibit Plk1 using a radioactive-phosphate incorporation assay. Assays were carried out in a mixture of 25 mM HEPES (pH 7.5), 10 mM MgCl₂, 0.1% BSA, and 2 mM DTT. Final substrate concentrations were 150 μM (350 μM for determining values of <1 nM) [γ-33P]ATP (115 mCi 33P ATP/mmol ATP, Amersham Pharmacia Biotech/Sigma Chemicals) and 300 μM (450 μM for determining values of <1 nM) peptide (KKKISDELMDATFADQEAK: SEQ ID NO: 1). Assays were carried out at 25° C. in the presence of 4 nM (1 nM for determining values of <1 nM) Plk1. An assay stock buffer solution was prepared containing all of the reagents listed above, with the exception of ATP and the test compound of interest. 30 μL of the stock solution was placed in a 96 well plate followed by addition of 2 μL of DMSO stock containing serial dilutions of the test compound (typically starting from a final concentration of 10 μM with 2-fold serial dilutions) in duplicate (final DMSO concentration 5%). The plate was pre-incubated for 10 minutes at 25° C. and the reaction initiated by addition of 8 μL [γ-33P]ATP (final concentration 150 μM (350 μM for determining values of <1 nM))).

The reaction was stopped after 90 minutes (240 minutes for determining values of <1 nM) by the addition of 100 μL 0.14 M phosphoric acid. A multiscreen phosphocellulose filter 96-well plate (Millipore, Cat no. MAPHN0B50) was pretreated with 100 μL 0.2 M phosphoric acid prior to the addition of 125 μL of the stopped assay mixture. The plate was washed with 4×200 μL 0.2M phosphoric acid. After drying, 100 μL Optiphase ‘SuperMix’ liquid scintillation cocktail (Perkin Elmer) was added to the well prior to scintillation counting (1450 Microbeta Liquid Scintillation Counter, Wallac).

After removing mean background values for all of the data points, Ki(app) data were calculated from non-linear regression analysis of the initial rate data using the Prism software package (GraphPad Prism version 3.0cx for Macintosh, GraphPad Software, San Diego Calif., USA).
